I've always loved to play games, and face it: investing is one big game. You need to be decisive, open-minded, flexible and competitive.

Our volunteers are flexible, open-minded and have a sense of humor.

I believe that good investors are successful not because of their IQ, but because they have an investing discipline. But, what is more disciplined than a machine? A well-researched machine can make many average investors redundant, leaving behind only the really good human investors with exceptional intuition and skill.

We want to go into every game being competitive. We don't want to go into games thinking about last year's record. We might lose a couple games, but I don't want people to say 'Here we go again. Same thing.' We need support from the crowd.

Whenever I see a stock market explode, six to 12 months later you are in a full blown recovery.

If machines do everything well, including allocating capital and resources efficiently, can that be deflationary, can that eliminate poverty? I don't know. It's hard to be very optimistic if you look at how humans have behaved historically.
